A friend told "Us Weekly" magazine: "She looks like the old Jennie! When you get sad, you either overeat or you become really healthy. Jennie's taking care of herself -she's taken control of her situation. Before, she used to be like: "OK, let's cover me up". And now she's more open-minded about having fun with her clothes. She's feeling good in her skin."

Jennie admitted in a recent interview that her weight loss is a direct result from her split, because her feelings are so heavily tied to her diet.
